Black screen with cursor on startup following Windows Update

Ah, I see. Nope, I didn't before, either.

I looked in the manual, and it said Del was the one used. When I press that repeatedly, the black screen with a cursor never appears, and the computer doesn't complete its startup, so it would seem like I'm in the BIOS. I have tried, using user manual screenshots, to navigate to 'Load Fail-safe defaults', but so far no luck.

Just bumping this to update: Regardless of what I press, I can't get the supposed BIOS menu to coorporate.

Have you tried running with just your CPU and one RAM module in the system to see if you can get into the BIOS? Sometimes, a failing piece of hardware can prevent the BIOS from opening properly.

• If you swap or remove any components, follow these steps for ESD safety:
  
  1. Shut down and turn off your computer.
  2. Unplug all power supplies to the computer (AC Power then battery for laptops, AC power for desktops)
  3. Hold down the power button for 30 seconds to close the circuit and ensure all power drains from components.
  4. Make sure you are grounded by using proper grounding techniques, i.e. work on an anti-static workbench, anti-static desk, or an anti-static pad. Hold something metallic while touching it to the anti-static surface, or use an anti-static wristband to attach to the anti-static material while working.
  
  Once these steps have been followed, it is safe to remove and replace components within your computer.

Hello, I have good news! Evidently, the drivers I installed at the time swapped something with the monitor plugs around, so one of the others became the one to recieve all the input from the computer instead. Regardless of what happened, or how, I had to use another plug for my monitor, something the computer gave no indication of. I'm sorry to anyone whose time I wasted, but also massively relieved that there wasn't a problem as serious as I feared.
Thank you guys for being so helpful, expecially Kaktussoft for his patience :)
